This is an original 1956 Hudson Hornet Special V8 Carter Carburetor 2352SA.  Good looking condition, not stuck-see photos.  Has been rebuilt, but not sure how long ago-see photos.  This came from an older parts dealer that has recently closed up shop. Carter book shows this fits: 1956 Hudson Hornet Special V8; 1956 Nash Ambassador Special V8 and 1957 Rambler V8.   Please check my other auctions.
